_H_y_p_e_r_b_o_l_i_c _F_u_n_c_t_i_o_n_s

_D_e_s_c_r_i_p_t_i_o_n:

     These functions give the obvious hyperbolic functions. They
     respectively compute the hyperbolic cosine, sine, tangent,
     arc-cosine, arc-sine, arc-tangent.

     cosh(x)
     sinh(x)
     tanh(x)
     acosh(x)
     asinh(x)
     atanh(x)

_A_r_g_u_m_e_n_t_s:

       x: a numeric vector

_S_e_e _A_l_s_o:

     'cos', 'sin', 'tan', 'acos', 'asin', 'atan'.
